HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 498 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 949, 498 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 949, 498 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 949, 498 is 1.
HCF(949, 498) = 1
HCF of 949, 498 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 949, 498 is 1.
Highest Common Factor of 949,498 is 1
Step 1: Since 949 > 498, we apply the division lemma to 949 and 498, to get
949 = 498 x 1 + 451
Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 451 and 498, to get
498 = 451 x 1 + 47
Step 3: We consider the new divisor 451 and the new remainder 47, and apply the division lemma to get
451 = 47 x 9 + 28
We consider the new divisor 47 and the new remainder 28,and apply the division lemma to get
47 = 28 x 1 + 19
We consider the new divisor 28 and the new remainder 19,and apply the division lemma to get
28 = 19 x 1 + 9
We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get
19 = 9 x 2 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 949 and 498 is 1
Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(28,19) = HCF(47,28) = HCF(451,47) = HCF(498,451) = HCF(949,498) .
